NMT Spherical Roller Thrust Bearings Axial Heavy-Load Buffer Support Bearings For Vertical Heavy Industry Equipment
During operation of large vertical heavy-duty industrial equipment, main shafts endure continuous huge axial pressure accompanied by vibration and impact. Coaxial deviation easily occurs during assembly. Ordinary thrust bearings have no self-aligning function. Slight shaft inclination leads to partial pressure on rollers, resulting in rapid wear and peeling and shortened service life. Once bearings of vertical mills and extrusion machinery break down, complicated disassembly work brings high maintenance costs and hinders production. In addition, some working environments feature high temperature, setting strict requirements on heat resistance and anti-fatigue performance. The market demands spherical roller thrust bearings capable of automatically compensating coaxial deviation and sustaining continuous heavy axial loads.
Japan NMT optimizes the design of spherical housing washers and rollers for spherical roller thrust bearings to achieve reliable self-aligning performance. The bearings effectively offset mounting misalignment and prevent damage caused by uneven load distribution. Reasonably arranged spherical rollers bear heavy axial loads and tolerate incidental radial loads. Profiled rollers disperse impact stress and restrain stress concentration on contact areas. Fine heat treatment of raw materials improves dimensional stability and anti-fatigue performance under high temperatures.
The bearings are compatible with circulating oil lubrication and long-service-life grease lubrication. The robust rolling structure adapts to complicated working conditions including continuous heavy loads and intermittent impacts. Dimensions comply with universal industrial standards for convenient spare part replacement of various large vertical heavy machinery.
